Properties of Waves Flashcards
What is a wave?
A way of transferring energy through matter or space without causing any permanent displacement
What is a crest?
The highest point in a wave
What is a trough?
The lowest point in a wave
What is amplitude?
The height of a crest or depth of a trough, as measured from its rest position
What is wavelength?
Distance of one complete wave, crest to crest or trough to trough
What are the two types of waves?
Transverse and compression (longitudinal)
What are transverse waves?
Waves in which matter moves perpendicular to the direction of the wave
What are compression (longitudinal) waves?
Waves in which matter moves parallel to the direction of the wave
What is frequency?
The number of repetitive motions that occur in a given time
What is frequency measured in?
Hertz
What is the formula to find frequency?
cycle/secs
When frequency increases, wavelength _______.
Decreases
